HAND-CONTROLLED POWER-OPERATIVE MEAT-SAW.

Specification of Letters Patent.

Patented Sept. 8, 1.908.

Applicat on filed ember 23,1907. cerium. 398,744.

To all wlwm it may concern: Be it known that I, WILLrAM A. RUssELL, residing at Kent, in the county of Portage, and State of Ohio, have invented a certain 5 new and. useful'lrnprovement in Hand-Con trolled Power-Operative Meat-Saws, of which the following is a full, clear, and exact deaeration. v

e object of the invention is to provide an improved construction of meat saw especially adapted to the requirements of utchers for use infacilitating theirwork.

I am aware that hand'controlled power operated saws are old but they have received their power in such manner or have been mounted in such manneras not to permit them to have the capacity for use in the variety of positions desired. For example, certain of them have comprised a hanging frame supporting the saw and an electric motor, the entire apparatus which is bulky and of great weight being suspended from the ceilin This former type of device is not desira le for many reasons, .notably be cause of the inability to lift and lower the saw readily upon the articles to be cut and the fact of it being necessary to shift the material worked on to a position substantially beneath the saw before lowering it. In this old apparatus if the machine be turned away from the vertical and then lowered su ciently to contact with the material the.

swinging of themechamsm back to its vertical position will cause the saw to drag upon the meat block to the injury of the former. There have been certain other devices of the same generic design but many of them have failed to be of practicaluse either by reason of their complication-or lack of reliability and flexibility in their use.

'The structure which I have devised is ca-' pable of the widest latitudeoi adjustment.

and the work involyes the use of no overhead sup orts or superstructure and is capable of app ication in any place where any sort of ower is available. An embodiment thereof 1s described in the following specification, ref

erence being had tothe accompanying drawin s in which,

ratus, a vertical adjustment of the saw being indicated in dotted lines. Fig. 2 is a plan view of the same, and a lateral, angular ad- 'ustment of the saw being indicated in dotted jus tment, is

, lead from the opposite side.

J lifted to any height igure 1 is a side elevationof the appa ,obvious to everyone skilled'in the art,it ing possible to apply the device to any table,

erably provide a horizontal su rt' shaft A for the saw-frame, said shaft? e' at the back of the table B slightly at. oirethe level, of the same andsupported at eacli end on suitable brackets or standards of acrylicsired construction. Mounted on this. shaft is a sleeve C capableof being slid laterally along the saghe and also capable of rotation thereon. C nnected with the siecve by means of a ball and socket joint D which permits both la eia'l, vertical and turning adrectangular yoke E having telescopic connection. with the saw frame F. The saw frame has at its outer end a handle G b y which the device is manipulated and a transverse bearing H in which the saw shaft I is mounted, the saw J being rcferably located at one side of the frame w 1c the power connection. such as a flexible tube K oithe sort commonly used in dental engines being As illustrated, I ma provide the saw frame with a hook L suita 1y located and adapted to hang over 'and catch upon a retaining bar M or'similar device when the saw frame is swung upward into vertical position out of the way;

By the arrangement described it wili be quite clear that the adjustment of the saw to its work is in every practical sense universal. It canbe slid along the table laterall to. any part thereof, by reason of th mounted on the supporting shaft. said sleeve is rotatab e on the shaft. It can be swung laterally to any angle the ,ivotal connection withthe sleeve.

e s ecvc o It canbe I reason of the fact that by reason of f It a can eitwisted to any angle to the vertical by reason of the universal character'of the ivotal joint, this joint being. as. stated a all and socket. It can be advancedor retracted toward or from the edge of thetable by reason of the telescopic character'of. the -'sup-' It will thus be seen that porting frame.

end the can there is no character of work be pacity of my a 1th.. paratus, yet it is, absolutely.

steady and hel against displacement by thaf resistance of the material worked uponwith i out subjecting the hand to any strain what-e.-

ever. pendent of the character of motor employed, it being possible to use any source 0 which may rotary motion to the driving tube.

"f The simple character of installation wil Further the power connectionis indea pc'wver be at hand that will a without the addition of any parts which will interfere with the use of the table or the super-position of any structure of any character. I v Having described my invention, I claim: 1. The combination of a sup ort, means capable of sliding Substantially orizontally'i on said support, a frame so connected to sai" I means as to be capable of universal angular movement and composed of two parts slid-' saw, the combinati'on ofa table, a support thereon}. means ca able of moving on said supiportv laterally with respect tothe table, a

e attached .to said means and-capable of universal angular. movement with respect thereto a frame mounted to slide-telescopically on said-yoke, a saw rotatablymounted on said frame and ahfiexible power-connec- 25 tion for driving said saw. v

3. In a hand-controlled, power-operated saw, the combination of a sup ort, means capable of sliding substantially or izontally on said support a oke so attachedto said 30 means as to beica'pable of universal angular adjustment with respect thereto, a frame mounted to slide telescopically on said yoke, a saw-driving shaft rotatably mounted on said frame, a fiexible power connection for 35 said shaft,'1neans for guiding said frame and means for suspending it on said support when not in use.

' In testimony whereof, I hereunto affix my signature in the resen'ce of two witnesses.
